Abstract
|
|
|
Purpose : To examine the change in physical properties of contact lenses by networking alginate and carrageenan on contact lenses of different materials.
Methods : We evaluated the properties of one-day contact lenses with the same refractive power, namely, somofilcon A, etafilcon A, and hilafilcon B, by networking them with seaweed polysaccharides such as alginate and carrageenan. In addition, antimicrobial activity was evaluated using E. coli.
Results : The water contents and wettability of somofilcon A networked with alginate were significantly improved, while the oxygen transmissibility was slightly decreased. All contact lenses networked with polysaccharides were antibacterial.
Conclusions : The networked seaweed polysaccharide not only improves the moisture content and wettability of the contact lens but also has an antibacterial effect.
